{
    public function execute(\GearmanJob $job = null)

    }
}

Manage workers

yii gearman/start 1 // start the worker with unique id
yii gearman/restart 1 // restart worker
yii gearman/stop 1 // stop worker

Example using Dispatcher

Yii::$app->gearman->getDispatcher()->background('syncCalendar', new JobWorkload([
    'params' => [
        'data' => 'value'
    ]
])); // run in background
Yii::$app->gearman->getDispatcher()->execute('syncCalendar', new JobWorkload([
    'params' => [
        'data' => 'value'
    ]
])); // run synchronize

Example of Supervisor config to manage multiple workers

[program:yii-gearman-worker]
command=php [path_to_your_app]/yii gearman/start %(process_num)s
process_name=gearman-worker-%(process_num)s
priority=1
numprocs=5
numprocs_start=1
autorestart=true
